UNITED STATES PATENT 1,980,460 ADJUSTABLE SPRAY. NozzLn Sanford E. White, Santa Monica, Calif. y Application November 8, 1933, Serial "No. 697,155

2 Claims.

The invention involves a hose nozzle of the type in which there is a central, longitudinally .movable valve rod or member adapted to be 10' moved outwardly into the opening or mouth of the nozzle for the purpose of changing the stream into a spray.

Among the salient objects of this invention are to provide a nozzle of the character referred to in which the joint between two parts is eliminated and a one piece body is attached directly to the end of the hose with which it is to be used; to provide in a nozzle of the character referred to a .telescoping sleeve within the body and to the .20 end of which is the spray forming valve member moving longitudinally into and out of the discharge opening of the nozzle body to change the stream into a spray or to cut it off entirely, with a transversely disposed member through the wall of the body and having operative engagement with said sleeve for moving the same lengthwise, without forming a joint into the interior of the passageway which would cause or permit leakage;

,, to provide a simplified and practical means for this moving said sleeve and the valve portion thereof to conveniently and quickly change the form of the discharge from said nozzle; and, in general, to provide an improved and economical spray nozzle which will not leak.

In order to fully explain my invention, I have illustrated the same on the accompanying sheet of drawings which I will now describe.

Figure 1 is a side elevation of a spray nozzle embodying my invention;

Figure 2 is a longitudinal sectional view with inner parts in elevation;

Figure 3 is a transverse sectional view taken at line 3-3 of Fig. 2;

v Figure 4 is a side elevation of a slightly modified form of the invention; and

Figure 5 is an end elevation taken at the line 55 on Fig. 4.

Referring now in detail to the drawing, my in- ..vention as here illustrated for descriptive purposes consists of a nozzle body member 10, having a cylindrical bore 11, longitudinally therethrough, with a valve seat 12 formed at the outer or discharge end thereof, and at its other end said body is adapted to be attached to a hose 13.

* Mounted within said body 10, is a cylindrical sleeve 14, open at both ends, and at its forward end provided with a valve portion 15, extended centrally forwardly from said sleeve and connected therewith with the arms or connecting portions 15, said valve portion being adapted to be moved to and from the discharge end of said passageway and when in its outermost position,

its valve element 15 seats in the valve seat 12, whereby to close said discharge opening or mouth from said nozzle body. When partially extended said valve portion changes the discharge from said nozzle from a stream to a spray, in the usual manner.

As a means for moving said cylindrical sleeve and its valve portion, I have provided a trans- 7 versely disposed operating member or shaft 16, with a gear 17 on its inner end, a centering collar 18, a packing 19, and a securing bushing 20, all fitted within a transverse bore 21, in a transversely formed extension portion 21 of the nozzle 7 body, near the hose attaching end thereof, as clearly illustrated.

The cylindrical sleeve 14 is provided on its periphery or outer surface with transversely extending teeth, forming a rack longitudinally thereof, designated 22, and in mesh with the little gear 17 on said operating shaft 16, whereby the turning of said operating shaft 16, said cylindrical sleeve and its valve portion are moved longitudinally within said cylindrical bore in said body. It will be noted that the operating connection is within the body and with the outside or surface of said sleeve, whereby there is no leakage possible from the body of the nozzle. As one means for turning said operating shaft 16, I have shown an operating wheel or disc 23, by means of which said sleeve and its valve portion can be manually operated. In Figs. 4 and 5, I have shown a lever 24 connected with said operating shaft, and operable forwardly and rearwardly to turn said shaft, said lever being bent to overlie the body of the nozzle as shown for convenience.

I have thus provided an adjustable spray nozzle which is not jointed at the end connected with the'hose, which so frequently leaks, and which is more expensive to make, and have provided a nozzle which is leak proof. I do not limit the invention to the showing made, except as I may be limited by the hereto appended claims.

I claim:

1. A spray nozzle body having a cylindrical passageway longitudinally therethrough, one end thereof being adapted to be connected with a hose, a cylindrical sleeve, open at both ends and. slidably fitting Within said body and having at its outer end a valve portion connected with the body of the sleeve with arm portions, the outer end of said nozzle body having an annular valve seat around the outlet thereof to receive and be closed by said valve portion, an operating member inserted transversely through the wall of said nozzle body, and operating connections between outer end of said bore being provided with an annular valve seat therearound and its rearward end being provided with means for connecting it with a hose, said body having a transverse bore through its body wall opening into the inside of said body, a cylindrical member slidably fitting within said body and open at both ends, a valve portion connected with the outer end of said member .and adapted to ,fihand clpse said valve seat, -an ioperating shaft in said transverse bore and provided'with a gear between the inside of 'said body and the outside of said sleeve, said sleeve having rack teeth cut in its outside to receive said gear, whereby the turning of said shaft .and meansjor turning said shaft in opposite directions.
